Convert Degrees to Feet and Inches Calculator

Reviewed by Calculator Editorial Team

This calculator converts an angle in degrees to a distance measurement in feet and inches. It's useful for construction, surveying, and any application where you need to translate angular measurements into linear dimensions.

How to Use This Calculator

To convert degrees to feet and inches:

  1. Enter the angle in degrees in the first field
  2. Enter the distance from the angle's vertex to the point of measurement in feet
  3. Click "Calculate" to see the result in feet and inches

The calculator will show you the horizontal distance from the vertex to the measurement point, expressed in both feet and inches.

Formula Explained

The conversion uses basic trigonometry to calculate the horizontal distance based on the angle and the distance from the vertex.

Formula: Distance (feet) = Distance from vertex × sin(angle in radians)

Where angle in radians = angle in degrees × (π/180)

After calculating the distance in feet, the calculator converts the decimal portion to inches (12 inches = 1 foot).

Worked Examples

Example 1: 30° Angle

If you have a 30° angle and the distance from the vertex is 10 feet:

  1. Convert 30° to radians: 30 × (π/180) ≈ 0.5236 radians
  2. Calculate distance: 10 × sin(0.5236) ≈ 5 feet
  3. Convert to feet and inches: 5 feet 0 inches

Example 2: 45° Angle

For a 45° angle with a 10-foot distance from the vertex:

  1. Convert 45° to radians: 45 × (π/180) ≈ 0.7854 radians
  2. Calculate distance: 10 × sin(0.7854) ≈ 7.071 feet
  3. Convert to feet and inches: 7 feet 1.32 inches (approximately 7 feet 1¼ inches)

Note: The calculator rounds inches to two decimal places for precision, but you may round to the nearest quarter inch for practical measurements.

Frequently Asked Questions

What is the difference between converting degrees to feet and inches?

Degrees measure angles, while feet and inches measure linear distances. This calculator converts an angular measurement to a linear distance based on the given distance from the angle's vertex.

When would I use this calculator?

This calculator is useful in construction, surveying, engineering, and any field where you need to determine horizontal distances based on angular measurements.

Is the result accurate for all angles?

Yes, the calculator uses precise trigonometric functions to calculate the distance for any angle between 0° and 90°.

Can I convert inches back to degrees?

No, this calculator only converts degrees to feet and inches. For the reverse calculation, you would need a different tool that measures the angle based on known distances.
